An assessment of stubble buckwheat productivity in Ukraine in changing climate conditions

Abstract

This article analyses the post-harvest agroclimatic resources based on the buckwheat productivity in Ukraine in changing climate conditions. The au¬thor performed calculations to obtain information on the agroclimatic conditions of the formation of four agroecological productivity categories for long-term annual average data (1986—2005) based on a climate change scenario for 2011—2030. The calculations made it possible to identify the areas of possible and economically feasible cultivation of buckwheat in Ukraine.

The abundance and territorial distribution of the Eurasian Coot (Fulica atra) and Common Moorhen (Gallinula chloropus) in Kaliningrad

Abstract

This article studies the Coot and Moorhen breeding in urban conditions. Seven years’ (1999—2003, 2006 -2007) field studies resulted in the compilation of an atlas of the Kaliningrad region’s nesting birds. The city territory was divided into 206 plots of an area of 1 km2. The urbanisation rate was estimated on a scale of 1 to 5. Kaliningrad is home to 208 breeding pairs of coots and 56 of moorhens. The Coot is more widespread (present in 25.2 % of the plots) than the Moorhen (13.6 %). The population density of the Coot reaches 10—15 pairs per km2 in the most suitable habitats with an average density of only 4.0 pairs per km2. The population density of the Moorhen reaches 5 pairs per km2 in optimal habitats with an average density of 2.0 pairs per km2. A negative correlation between the number of birds and the urbanisation rate of the city territory is observed in the Moorhen (r s = — 0.44; P <0.05). The breeding area of the Moorhen has increased over the last decades. The Coot breeding area has not changed significantly, whereas the population density has increased.

Metal accumulation in urban ecosystem plants

Abstract

The paper presents the results of a study of metal accumulation (Cu, Zn, Mn, Sr, Ni, Ca, Fe, Br, Rb) in the leaves of trees, shrubs, and herbaceous plants (a total of 22 species) in the urban environment of Kaliningrad. The study area includes major geochemical landscapes – residential, industrial, and recreational districts. The background concentration of metals in plants is studied. The study establishes the presence of significant anthropogenic sources of metal pollution of vegetation in Kaliningrad. The leaves of plants found in the urban environment show excessive background concentrations of iron, manganese, zinc, and strontium. The maximum content of pollutants in plants is registered in industrial areas with high traffic load. Species-specific features of metal accumulation are established. Plants with a high metal accumulation capacity can be used in the phytoremediation of polluted urban areas.

The human impact on the chemical composition of plants in large industrial centres: The case of the city of Gomel

Abstract

This article considers the features of heavy metal accumulation in individual plants of the true grasses and spurge families in two industrial areas in the city of Gomel and outside the city. The author analyses the heavy metal accumulation in the aquatic vegetation in the city’s waterways. It is shown that, in industrial areas, the Gramineae are charactersied by higher cadmium, barium, nickel, and molybdenum concentrations and the Euphorbiaceae by those of chromium. Aquatic plants show higher levels of heavy metal accumulation in comparison with meadow vegetation.

Sustainable tourism as an alternative development path for coastal towns: The case of the Kaliningrad region

Abstract

The authors present a function-based typology of towns located on the coast of the Kaliningrad/Vistula Lagoon. It is shown that the recreational function of these towns is either poorly developed or absent, which complicates the sustainable development of coastal territories. Grade-based assessment makes it possible to identify factors both facilitating and hindering the recreational development of coastal towns. Towns with the highest recreational potential are identified.
